5 mm Arm Sealers, No Cutter

To operate set to #1 and press the arm down to seal. Hold it down a couple seconds. Remove bag and test seal.  If not sealed adjust the setting to 1 1/2 and repeat. Keep repeating until you have a good seal. Avoid using more heat than necessary and never heat long enough you can just tear the bag off at the seal point.  This will cause premature wear on the Teflons and wire.
